Rivera continued, "That's when it started, really early at nine in the morning. I came to my mom's house. We started getting the news. Then at around 5 p.m., we got confirmation that she was gone. It was so painful."

Pedro tells E! News that the whole family is together now, except for his brother Lupillo, who is currently in North Carolina and flying out tomorrow, and that they're planning to fly out to Mexico once the family receives more information.

"When we do find out what has happened with the body, because they have to get it out of the woods there. As soon as they get the bodies out and we receive the news that they're there, all the family is gonna fly over there and bring our sister back."
